Address review feedback: restructure plugin for marketplace conventions

- Remove .mcp.json (not used in marketplace, add README instead)
- Add marketplace.json entry for plugin discovery
- Add README.md with MCP server setup guide, provider config, and troubleshooting
- Add tools: declaration to image-generator agent (functional fix)
- Move <example> blocks from YAML frontmatter to markdown body
- Remove unused tools: Read, Grep, Glob from prompt-crafter agent
- Remove redundant name: field from command frontmatter
- Use full MCP tool prefix (mcp__meigen__*) in commands
- Rewrite plugin.json description to factual style
- Pin npm version to meigen@1.2.5

+# MeiGen AI Design
+
+AI image generation plugin with creative workflow orchestration, parallel multi-direction output, prompt engineering, and a 1,300+ curated inspiration library.
+
+## Prerequisites
+
+This plugin requires the **meigen** MCP server. Install it by adding to your project's `.mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "meigen": {
+      "command": "npx",
+      "args": ["-y", "meigen@1.2.5"]
+    }
+  }
+}
+```
+
+**Restart Claude Code** after adding the configuration.
+
+Requires Node.js 18+.
+
+## Provider Setup
+
+Configure at least one provider to enable image generation. **Free features** (gallery search, prompt enhancement, model listing, preference management) work without any provider configured.
+
+### Option A: MeiGen Cloud (Recommended)
+
+1. Sign up at [meigen.ai](https://www.meigen.ai)
+2. Click avatar → Settings → API Keys → create a new key (starts with `meigen_sk_`)
+3. Set environment variable:
+
+```bash
+export MEIGEN_API_TOKEN=meigen_sk_your_token_here
+```
+
+### Option B: Local ComfyUI (Free, Private)
+
+1. Install and run [ComfyUI](https://github.com/comfyanonymous/ComfyUI)
+2. Set environment variable:
+
+```bash
+export COMFYUI_URL=http://localhost:8188
+```
+
+3. Export workflows from ComfyUI (API format JSON) and import via the plugin
+
+### Option C: OpenAI-compatible API (Bring Your Own Key)
+
+Works with any OpenAI-compatible image generation API (OpenAI, Together AI, Fireworks AI, etc.):
+
+```bash
+export OPENAI_API_KEY=your_key_here
+export OPENAI_BASE_URL=https://api.openai.com/v1
+export OPENAI_MODEL=gpt-image-1
+```
+
+Alternatively, store configuration in `~/.config/meigen/config.json`.
+
+## Agents
+
+| Agent | Model | Purpose |
+|-------|-------|---------|
+| `gallery-researcher` | haiku | Search 1,300+ curated gallery, find references, build mood boards |
+| `prompt-crafter` | haiku | Write multiple distinct prompts for parallel image generation |
+| `image-generator` | inherit | Execute `generate_image` calls and relay results |
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `/meigen-ai-design:gen <prompt>` | Quick image generation — skips intent assessment |
+| `/meigen-ai-design:find <keywords>` | Quick gallery search — browse inspiration |
+
+## Free Features (No API Key)
+
+These tools work immediately without any provider setup:
+- **search_gallery** — Search 1,300+ curated AI image prompts
+- **enhance_prompt** — Expand brief descriptions into detailed generation prompts
+- **list_models** — List available models across all configured providers
+- **manage_preferences** — Save default style, aspect ratio, and favorite prompts
+
+## Verification
+
+After setup, test with a free feature:
+> "Search the gallery for product photography inspiration"
+
+Then test generation:
+> "Generate a product photo for a glass perfume bottle on marble"
+
+## Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| MCP tools not available | Restart Claude Code after adding `.mcp.json` configuration |
+| "No image generation providers configured" | Configure at least one provider (see Provider Setup above) |
+| API key / authentication errors | Verify env vars or check `~/.config/meigen/config.json` |
+| ComfyUI connection refused | Ensure ComfyUI is running at the configured URL |
+| Generation timeout | Server may be under high load — try again in a moment |
+| Empty gallery search results | Try different keywords or broader terms |
